[arch-general] ACL on /dev nodes (systemd, lightdm)

[Damjan]

Hi all,
I know systemd and lightdm are not exactly kosher on ArchLinux, but any
help would be welcome.

So, I just noticed that OpenGL is using llvmpipe on my laptop, and then
I found out that the /dev/dri/card0 node doesn't have the proper ACL set
to allow access to my user. Also my user is not in the video group -
since I've learned that's not necesseary in "modern" Linux configurations.

Considering that I'm running systemd and using lightdm as a login
manager - my question is, what subsystem is responsible for settings the
ACL:
- ConsoleKit
- PolicyKit
- systemd
- lightdm
?


Is the proper setup to have pam_loginuid.so, pam_ck_connector.so and
pam_systemd.so in the PAM configuration for lightdm?



the output of ck-list-session is:
Session2:
	unix-user = '1000'
	realname = ''
	seat = 'Seat1'
	session-type = ''
	active = TRUE
	x11-display = ':0'
	x11-display-device = '/dev/tty7'
	display-device = ''
	remote-host-name = ''
	is-local = TRUE
	on-since = '2011-12-02T18:23:04.193636Z'
	login-session-id = ''
